o Clicking Geo mode: the gimbal stares at the LLA in the center of the video
o Double clicking on the map: the gimbal stares at the location clicked
o Selecting a preloaded geopoint: the gimbal stares at the geopoint LLA
Mode limitations: operators will notice that at narrow fields of view, the gimbal will slowly
oscillate about a target which is a consequence of errors in the gimbal attitude solution. For this
reason, Scene Mode described below is most commonly used at narrow fields of view. Geo mode
may behave poorly if the gimbal is located near the ground due to errors in the GPS altitude and the
ground elevation model. Therefore, Geo mode should not necessarily be expected to work
accurately unless the gimbal is at least 50 to 100 feet above the ground.
Scene Mode
In Scene mode, the gimbal uses video processing feedback to continue looking at the current video
scene. In a similar manner as Geo mode, Scene mode will keep the gimbal staring at a location on
the ground regardless of gimbal movement. Once in Scene mode, a user can click on the video to
direct the gimbal to stare at a new location or use the onscreen joystick to steer the gimbal.
Mode limitations: for Scene mode to work well, there must be sufficient image content for the
onboard video processor to lock on; when operating over water, sand, or when using IR cameras in
situations with poor contrast, Scene mode will result in erratic behavior. In these cases, Geo mode
should be used instead. Please see Automatic Gimbal Mode Transitions section for anticipated
behavior.
Track
NOTE: Track mode required an optional feature to be included in the gimbal and additional
hardware is installed to enable this mode. Without the tracking option installed the Track Mode
button will not appear and this feature is not available.
Commands the gimbal to use Track Mode. Will be highlighted when the gimbal is in Tracking mode.
In Track Mode the gimbal will track a specific target and attempt to keep it in the center of the
video. Clicking the Track Button will put the gimbal in track mode; to start tracking an object
simply select/click the object in the video. Clicks on the video while in Track Mode will cause the
gimbal to start tracking the target that was clicked on.
To quickly begin tracking an object regardless of current gimbal mode, right click it on the video.
Mode limitations: Tracking requires a clear LOS of the target to maintain a Track. While the
tracking algorithm has capability to coast and resume lost tracks, it is typically better to operate in
SCENE Steering mode in situations where the LOS will be occluded by trees, buildings, etc… Please
see Automatic Gimbal Mode Transitions section for anticipated behavior when Track mode drops.
Automatic Gimbal Mode Transitions
The gimbal will automatically transition between operation modes when it loses the ability to
maintain the current mode. Example is when scene mode loses confidence due to low scene content
